Camouflage is a clever trick that some animals use to blend in with their surroundings. Imagine playing a game of hide and seek, but you're wearing a special suit that makes you look just like the wall or the tree you're hiding behind. That's what camouflage is like for these animals. It's like a special suit or skin that helps them hide from predators or catch their prey easier. Animals can have spots, stripes or colours that match their environment, making them hard to spot. Some animals like chameleons can even change their colour based on where they are!
Think of camouflage as a superhero's invisibility cloak that animals use in their day-to-day life.

Camouflage is an evolutionary adaptation, which means it's a change that has occurred over a long time to help animals survive in their environment. It's not just about blending in with the surroundings, but also about mimicking specific objects or patterns. For example, the leaf-tailed gecko has a body shape and colour that makes it look like a leaf, making it almost invisible in the trees.
There are several types of camouflage. Cryptic colouration helps animals blend in with their environment. Disruptive colouration uses bold patterns to break up the animal's shape and make it hard to identify. Lastly, countershading, where animals are darker on top and lighter underneath, helps them look flat and less 3D, making them harder to spot.
Imagine a soldier in a war wearing a camouflage uniform, blending in with the trees and bushes to avoid being seen by the enemy. That's what animals do, but naturally.
Imagine you have a pile of Lego bricks in different colours: green, brown, blue and white. Now, you need to build a Lego animal that can hide in a forest made from green and brown Lego bricks. You would use green and brown bricks to build your animal, right? That's exactly how animal camouflage works.
Some animals are like chameleons, they can change the colour of their Lego bricks based on where they are. So, if the chameleon moves from the green and brown forest to a blue and white Arctic landscape, it changes its green and brown Lego bricks for blue and white ones to stay hidden.
In the world of survival, animals are like Lego master builders, constantly adapting their 'build' to seamlessly blend into their ever-changing environment.

Camouflage is a complex biological process, underpinned by the principles of natural selection. Animals with effective camouflage have a higher likelihood of survival and, thus, passing on their genes. Over time, this results in the prevalence of camouflage traits within the species.
The genetic basis for colour and pattern variation is complex and multifaceted. For example, the peppered moth's colour change from white to black during the industrial revolution is a famous example of rapid evolutionary change in response to environmental conditions.
Biochromes, naturally occurring pigments found in many animals, are responsible for the vast range of colours seen in nature. Some animals, like cuttlefish and chameleons, can actively control these pigments, allowing them to change colour almost instantly.
Picture a chess game where the pieces evolve to blend into the chessboard, making it difficult for the opponent to identify them. That's the intricate game of survival animals play with camouflage.
